GLITCH.

A circle expands. The movement is always smooth. But sometimes — it glitches. Stutter. Skip. Flicker. Reverse. Speed Burst. Wobble. Tap the exact moment you catch the glitch. Miss it, or tap when there's nothing wrong, and you lose a life. As your score climbs, the circle moves faster and the rewards grow bigger. Chain catches for streak bonuses. Survive all five levels. Simple to learn. Hard to master.
